Our synthesis of current research findings reveals that specific low-cost and environmentally friendly modification techniques can significantly enhance the hydrogen …
Metal hydrides have higher hydrogen-storage density ( 6.5 H atoms / cm 3 for MgH 2) than hydrogen gas ( 0.99 H atoms / cm 3) or liquid hydrogen ( 4.2 H atoms / cm 3) [3]. Hence, metal hydride storage is a safe, volume-efficient storage method for on-board vehicle applications.

For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. The overarching challenge is the very low boiling point of H 2: it boils around 20.268 K (−252.882 °C or −423.188 °F).
The hydrogen storage by solid-state materials has definite advantages from a safety perspective.

Through the process of absorption, hydrogen is dissociated into H-atoms and incorporated into the solid lattice framework. Therefore, hydrogen gas can be stored in a small volume under pressure of 70 bar. This is much lesser than a conventional tank where hydrogen must be kept under pressure of more than 700 bar.
